This reverts commit 1ee494291880fd51ef0c5f7342e072bdb069d7ff.
Commit 1ee494291880 ("ata: fsl_ahci: Add sata DM support for Freescale
powerpc socs") introduced SCSI layer to call AHCI private API in order
to support sata operations, In DM mode, This is not necessary for
non-AHCI sata. So revert it and have already updated the driver itself
to operate sata directly.
